EDMUD H, BAERETT,

TlE-PLATE To all whom t lmay fo/.worn s Be it known that l., Enemies El. Banner-'n a citizen of the VUnited Stctesi residing at Butte, in the county of Siirerbow and State of Montana, have invented certain ne and useful Improvements in Tie-Plates, of which the following is a speciiication.

My invention relates to tie-plates and its purpose is to provide a tie-plate, or rail chair., which Will also act eiliciently as a rail anchor, or anticreeping device In the construction and maintenance of railways it is desirable to place metal plates on the ties beneath the rails in order to provide a seat, or a chair, for the rails which Will act in general to protect the ties and to prevent lateral turning o' he rails about their longitudinal Wi the con enr cutting of thebasdu tliereof' into .is. Furthermore, it is common tice to cmploy anti-creeping devices in order te 'pre vent the longitudinal cre )ing or drifting of the rails on the ties under the iniuence of the`roll'ing stock. These antiefcsrcepers besides being bulky and cumbersome are often' complicated and ineiiicient and are embodied in structures sepan and distinct from the usual tie-plates, thus greatly increasingthe cost of track equipment and maintenance. 1 have therefore provided combination tie-plate and anti-Creeper, Whi ch is simple, rugged, and economical in construction; durable in use, efficient in operation.

My invention simplifies the construction and avoids duplication of elements for different purposes Without sacriiice of fun cti on or eiciency.

A `tie-plate constructed in accordance with my invention also operates to preventthe shearing of ,spikes owing to the lateral thrusts of the rail base, and further 'feature of my invention is that it embodies im proved means for preventing the dispiace ment of the plate relative to the tie.

Other objects and advantages of my in vention will be set forth in the fol'ewing specification, taken in connection with the accompanying drawings? in Wl b. I have shown my invention unifiedY in a convenient and practical torni.

spect to the base of a rail-11. The pla 10 'I y.

has formed thereon an `upwardly and in; wardly turned hooked. jaw, or shoulde'r;

which is adapted to contact with aportinl or" the upper surface of one side of the milf;-

base when the rail is in operative position/'j'l with respect thereto. The distance tween the lower surface of said jaw and theft upper surface of the plate should preferably'- 70 he such that said jaw will firmly grip the i rail base before the lateral edge of said base comes in Contact with the lateral surface-.of

the aperture, or groove, beneath said javviA Spiking apertures 13 are provided in the plate on the side thereof adjacent the javv 12 and preferably spaced outwardly from the inner edge of said jaw, such that spikes driven therethrough will not engage thegadjacent edge of the rail base in such a manner as to prevent the gripping of said rail base by the jaw l2 when the rail is forced toward said jaw. yThe plate 10 is .provided onthe side thereof opposite the jaw 12 with lother spiking apertures 14, Which are so spaced from the jaw 12 and spiking apertures' 13 that when the under surface of the jaw 12 is i Contact with the adjacent edge .of the rail hase 'the inner boundaries 14 of said apertures 1% will lie inwardly of the lateral edge il of the rail base, as clearly shown in the drawings. The spiking apertures 14v are further provided of tuch size that the usual spikes 15 driven therethrough will tightly wedge between the outer surfaces 14b of said apertures and the adjacent lateral edge 1.1a of the rail base, thereby causing the rail base to be tightly gripped between said spikes and the opposite hookedl jaw 12, tlius el'iciently holding the rail against longitudinal creeping thereof under the intluence, et the rolling stock. a f

4rt will he understood that the gri l*ping of 'l to prevent creeping thereof,y ay also he acconrg'ilished by loca-ting" the spi/king apertures i3 inwardly of the platf to such a-cffr- 'to be firmly held by the Wed'ging Spikes at opposite sides thereof. It y1s preferable',l

' l f :ace of the plate under the infiuence of the opposite wedging spikes 15, since a veryv large resistance to the creeping of the rail is thereby presented. For this purpose it is desirable to provide-'a relatively large area of contact between the jaw 12 and the upper surface of the rail base, in order to increase the rictional resistance to movement of the rail.

VThe under side of the plate 10 is provided with Series of relatively transverse ribs 16, preferably Aof a knife edge form and arranged at an inclination tothe principal axes of said plate. These ribs 16 are adapted to enter the fibers of the tie and prevent displacement of the plate relative thereto. If desired additional ribs 17 may be pro* vided along the lateral edges of said plate. The ribs 16 are preferably arranged at an angle to the axis of said plate, as shown, in

order that they will readily enter the fibers of the tieA when the plate tends to move lat- .erally, and in order that the fibers of the tie will be wedged between said ribs when a pressure is exerted on the plate after said ribs have become embedded in the tie.

.It will be apparent that. I have provided an improved tie-plate which acts as a chair, or support, for the rail and also operates efficiently to prevent longitudinal creeping of the rails relative to the ties. It will further be evident that when my tie-plate is used with the j aw 12 toward the outer side of the railway track, said jaw, or shoulder,

will operate to prevent the shearing of the spikes, which pass through the apertures 13,

owing to the lateral thrust of the rail.

Vhile I have shown and described a particular form which my invention may take,

it will be understood that it may be embodied in other structures of widelyldivergent form, and I therefore do not wish to be limited in the scope of my invention. except' as defined by the appended claim.

vI claim:

In a. .device of the class described, a plate adapted to rest upon a. tie and supportl va rail, said plate having an upwardly and inwardly directed jaw adapted to engage the upper surface of a rail base, said jaw being formed to leave a clearance between the lateral edge of said rail base and the junctionof the lower surface of said jaw with the upper surface of said plate, said plat-e having a spikingaperture adapted to be overlapped by the edge of the rail base opposite said jaw .when'said rail base is in .contact .with said jaw, the uncovered portion of said EDMUND H. BARRETT.
